These versatile intrinsically safe Timer or Clocks can perform a host of timing and control functions such as sampling or dosing within a hazardous area. An easy to use state and event structure enables relatively complex timing functions to be easily configured. Timing operations may be started and stopped via the inputs, or from the front panel buttons. The instrument display shows progress of the operation and international certification permits worldwide installation.

An internally powered backlight is available as a factory fitted accessory.

Timer or Clocks can be supplied configured and fitted with a customer specified printed scale card showing the units of time for no additional charge. An optional stainless steel legend plate is also available which can be supplied laser engraved with customer specified tag and application information.
